Maintenance and Care
Please do not forget that the safe operation of lamp heads also includes their maintenance and care. A visual inspection should be conducted before every use, and an inspection of electrical safety should be conducted at least once every 12 months. The results of these repeated inspections should be documented and filed. You will find additional information for the setup and operation of your lamp head, as well as information on the special features of the individual lamp head models, in the relevant operating instructions. Our recommendations for maintenance of this lamphead can be found on the following pages.
Visual Inspection
We recommend a regular visual inspection. This helps to detect potential damages in an early state. This is the only way to prevent and avoid consequential damage to other components. If your lamp head shows any visual damage, please contact your local ARRI service partner.
Cleaning The lamp head should be cleaned regularly. This is not just for your own safety; it also increases the lifespan of the device significantly. The following components should be cleaned regularly:
1. Cleaning the UV protection glass: Use conventional glass cleaner and a soft cloth for cleaning the protection glass.
2. Cleaning the reflector:
Follow the steps for “Lens holder” and “Reflector” Use conventional glass cleaner and a soft cloth for cleaning the reflector.
3. Cleaning the inner housing:
Follow the steps “Lens holder” and “Housing” in this manual. Clean the inner housing carefully with a vacuum cleaner and get rid of dust and
insects.
Testing of Mechanical Components
The following mechanical components should be checked regularly for functionality:
1. Safety switch:
When setting or checking the safety switch you must ensure that you hear the clicking noise 2 times before the lens door is closed completely. If you are not sure if your lamp head is set correctly please contact immediately your local ARRI service partner for more information on how to proceed.
2. Lamp socket:
Burn marks or discoloration may be an indication for contact problems. We strongly recommend a replacement to avoid damage on the lamp head. Please contact your local ARRI service partner for more information about how to adjust the lamp socket correctly.
